道路

For tips on how to best handle traffic, see Traffic.

Roads are the main city infrastructure and the backbone of every city. They are the most most basic and important tool for building cities. There are several different types of roads available and they serve mainly two purposes: traffic and zoning. At the start of a new city, only the two-lane road is available. More types of roads are unlocked after building the first road, and the rest are unlocked through milestones.

All road types aside from highways have a power line capacity of 40 MW (Low Voltage). Those that aren't bridges also carry water and sewage pipes.

Certain road types are more suitable for residential zones and some for faster and heavier traffic. Some of the higher capacity roads such as highways do not even allow zoning next to them. Vehicles on larger roads also tend to generate more noise pollution and decrease the land value around them.

Driving side

When creating a new city, the side of the road on which vehicles drive can be selected. Right-hand-drive is the default. The driving side cannot be changed later in the game.

Development tree for roads

To unlock most features related to roads, you will need to unlock them via the progression panel. These include features such as highways, large roads, larger size roundabouts, parking areas and road upgrades like trees, grass and wider sidewalks.

Road construction and tools

The road tools

By default roads will snap to zoning cell length, 90° angles, the sides of a building, zone grid, guide lines and existing geometry. This behavior can be turned off in the construction menu.

Tool mode

The Tool Mode determines the shape of the roads. There are six different options for drawing roads, which are listed below. A hotkey can be assigned to cycle through the various tool modes.

1. Straight: First click determines the start point. Second click determines the end point.
2. Simple Curve: First click determines the start point. Second click determines the bend. Third click determines the end point.
3. Complex Curve: First click determines the start point. Second click determines the first bend. Third click determines the second bend. Fourth click determines the end point.
4. Continuous: First click determines the start point. Second click determines the first bend. Third click determines the end point. Subsequent clicks create additional bends and end points.
5. Grid: Create two initial points and then drag sideways to create a perfect grid.
6. Replace: Hover over an existing road to replace a segment with a new road type. If the new road had a different width hovering over the left, right or center determines where the new road is placed.
   1. The replace tool is also used to add tram tracks and bus lanes onto some road types, but must be accessed from the transportation menu once it has been unlocked. Tram tracks cannot be added to highways, alleys, gravel roads, and some bridges.

Elevation

Elevation determines the elevation of the road compared to the start point and can be used to make roads go above and underneath each other without creating intersections. The Elevation step setting can be used to set elevations in increments of 1.25, 2.50, 5.00, 10.00 meters (3.75, 7.50, 15.00, and 30.00 feet).

Parallel mode

Parallel Mode will create two roads perfectly side by side. The offset determined the distance in zone cells between the two roads and can be set from 0.25 to 12.

Snapping

Several snapping options are available to refine your road placement which are listed below.

1. Toggle all snapping on/off: Toggles all snapping options listed below. Can be assigned a hotkey.
2. Snap to existing geometry: Allows snapping to roads, pathways, and other transportation networks.
3. Snap to zoning cell length: Allows snapping to the zoning cell length, in other words snaps every 8 meters (8.7 yards).
4. Snap to 90 degree angles: Allows snapping at 90 degree angles. Useful after building the first segment of a road, and aligning grids.
5. Snap to the sides of a building: Allows snapping to the sides of any building, including zoned buildings, where the point selected will be directly adjacent to the building snapped to.
6. Snap to guidelines: Allows snapping to guidelines from other roads and networks. Useful when connecting different road networks & grids, building highways ramps, and aligning curves. Can often break grids if left on while building road networks.
7. Snap to zone grid: Allows snapping to the best available zone grid beneath the cursor, not always the zone grid that the road started on.

Miscellaneous

The Show contour lines is shown in-line with the snapping tools but is not a snapping option. Toggles the terrain contour lines seen on the Landscaping/Terraforming menu.

Directions

One-way roads allow traffic in one direction only and can decrease traffic congestion. The direction in which the road is drawn also determines the direction of the traffic. Traffic will move from the starting point to the end point of the road. One way roads include most highways and highway ramps, so make sure to place highways in the right direction. Service vehicles cannot go against the flow of traffic and so even if a building next to a fire station is on fire if it is the wrong way down a one-way road the fire trucks will have to take the long route. Commercial and industrial buildings also require goods to be delivered and picked up, if they are unable to be serviced often enough on a one way road they may stop operating effectively.

Two-way roads allow travel in both directions. These roads can increase traffic congestion but allow for less restricted pathing for cars through cities and so small two-way roads make for ideal low traffic roads.

Roundabouts

Intersections and road ends can be replaced by roundabouts. The number of lanes on the roundabout depends on the number of lanes in the roads connecting to it. Vehicles entering the roundabout usually give way to those already on it but will cut in front of another vehicle already on it if a suitable opportunity arises. Roundabouts come in 4 sizes:

• Small roundabouts cost ₡ 200
• Medium roundabouts cost ₡ 500
• Large roundabouts cost ₡ 1000
• Very large roundabouts cost ₡ 1500

Road types

Most roads come in different sizes and configurations. The larger the road, the higher the speed limit and traffic capacity. The costs in the following table are not entirely accurate, because the costs depend on many factors.

Parking spaces

Parking spaces are an integral part of any city. Arranging facilities for residents and tourists traveling by car is an important factor in making the city a comfortable place. When residents and tourists plan their way around the city, their decision-making is affected by the availability of parking in a manner similar to public transport options.

Road services

Road maintenance depot

The Road Maintenance Depot, which sends out vehicles to keep roads in good condition, fighting wear and tear and decreasing the chances of traffic accidents. During winter, snowplows are deployed to keep the roads clear of snow. The Roads infoview shows data about the condition of the roads, coloring them from green (good condition) to red (poor condition). Poor road quality or excess snow slow down traffic and increase chance of traffic accidents occurring. Road Maintenance takes care of these traffic accident aftermaths, clearing out the debris and allowing traffic to continue safely after the police have secured the site of the accident.
